Abstract: Techniques related to demosaicing for digital image processing are discussed. Such techniques include correcting defective pixels by detecting hot and warm pixels and correcting such detected hot and warm pixels based on neighboring pixels and angle compensation including detecting dominant angles and compensating for such detected angles during demosaicing.

Abstract: One or more apparatus and method for compressing xvYCC or sRGB color to a narrower color gamut. Embodiments may be utilized in processing images/video image sequences provided in a wide gamut color space for display in standard RGB color space. In further embodiments, an sRGB or xvYCC compliant input is compressed to a gamut narrower than sRGB. Embodiments where a narrow output color gamut lacks a fully-defined 3D color space, semi-fixed-hue gamut compression may be performed by adjusting parameters provided to a fixed-hue compression module capable of mapping 3D color space representations between well-defined gamuts.

Abstract translation: 一种或多种用于将xvYCC或sRGB颜色压缩到较窄色域的装置和方法。 实施例可以用于处理在宽色域颜色空间中提供的用于在标准RGB颜色空间中显示的图像/视频图像序列。 在另外的实施例中，将sRGB或xvYCC兼容输入压缩到比sRGB窄的范围。 可以通过调整提供给能够在明确定义的色域之间映射3D色彩空间表示的固定色调压缩模块的参数来执行半输出色域缺乏完全限定的3D色彩空间的半固定色相色域压缩的实施例。
